I recently installed a new pellet stove of the Drolet (SBI-Quebec) Eco-45 variety. Using an exterior vertical flue and a fresh air intake kit, the stove is an excellent performer. Over the years I have spent some time successfully improving (tinkering with) wood stoves and wood furnaces to extract every available BTU from them. The balancing act was always to maximize heat transfer while keeping the flue gases hot enough to avoid the well-known problems, and to not overheat internal structures unless you really enjoy welding or replacing warped parts. So, it is wisdom born of experience that has so far kept the torch and hacksaw away from the new pellet stove. But naturally, I have to wonder about that baffle above the burn pot. The opening across the front of it is effectively a slot, maybe 12" x 1/2". That should keep the fire area hotter, and create turbulence as hot gases are forced up, back, and through the stainless steel heat exchanger above the baffle. But if the baffle were either removed, had some holes drilled in it, or the slot were enlarged to say 12" x 1", wouldn't the heat exchanger tubes reach a higher temperature (being careful not to overdo this) and thus be able to convey more heat to the air blowing through them? I can't wait to experiment with this. So my questions are: Has anyone learned any lessons from this kind of "tuning" of their pellet stove? Are there any gains (or losses I just don't foresee) to be had by altering baffle dimensions? Or, should I instruct my wife to hide all of the tools while I am not looking? Thank you for sharing your thoughts.
